Omar Perez explains the Seismic Nest of Bucaramanga as the primary source of Colombia's frequent seismic activity.

The Geological Service of Colombia (SGC) identified the Seismic Nest of Bucaramanga as a major geological structure responsible for the country's frequent tremors. Located under the municipality of Los Santos in the Santander department, this region concentrates approximately 45% of Colombia's seismicity. Omar Perez reported that the nest is formed by fragments of ancient tectonic plates submerged in the Earth's mantle, which interact to produce continuous seismic activity. This geological feature explains why the area experiences such frequent shaking, particularly following a 5.1-magnitude earthquake that recently struck the east and center of Colombia. The SGC noted that while Colombia experiences an average of 80 earthquakes per day due to its location in the Pacific Ring of Fire, many are not perceivable by the population. The Seismic Nest of Bucaramanga remains a key area of study for understanding the country's and its surrounding regions' seismic patterns.
